After the precise clinical, cephalometric and model analysis, the 27-year-old female patient was treated by removal of a section of bone from both mandibular second molar region. The results are as follows; 1. The postoperative cephalometric analysis reveals remarkable reduction of mandibular body length, ratio of mandibular body to anterior cranial base, SNB, ANB, SNPo, anterior face height. The surgical correction resulted in satisfactory cosmetic and functional improvement without any noticeable complications. 2. To control the axial inclination of upper and lower anterior teeth, minor teeth irregularities and to eliminate the premature contact, fixed type orthodontic appliances with occlusal equilibration have been performed for about one year.
